I know Mark (saintly) has kept them and seems to have had good experiences with them.
They are one of th emore aggresive tetras, so keep in good sized groups with no small, long-finned etc fish such as Guppies. Like jay said, they also grow quite large for a tetra (about 7-8cm maybe) so a tank of about 60cm/20gallons is a good sized tank for them. Nonetheless, quite an undemanding fish - obviously make sure your filter is cycled etc and they'll be fine with just the normal drill - weekly water change, flake food etc.
Hope this helps 😉
